"A couple of minutes after we sat down, a waiter came in with a bottle of champagne and a note that read 'will you marry me?'" Sarah recalled. She turned to Scott and found him on one knee, holding a cushion-cut diamond ring. "Fifteen minutes later, our mothers walked in—they had flown to D.C. without me knowing."
